“…Previous studies of China regarding the inter-organizational knowledge trading in supply chain focused on theoretical research, such as the influencing factors of knowledge market in supply chain and the theoretical research of knowledge trading modes (Zhang et al, 2006;Xu et al, 2008;Zhao et al, 2014). Then, considering that inter-organizational knowledge trading and cooperative innovation activities have certain social background and organizational context, scholars gradually introduced variables related to organizational context and empirically studied their influence on supply chain inter-organizational knowledge trading and enterprise performance, such as research on influence of characteristics of supply chain partners (Chen & Zhang, 2013), partnerships (including variables such as trust, relationship commitment and relationship quality) (Chen et al, 2012;Cheng & Fu, 2013;Chen et al, 2016), cooperative mechanisms (market mechanisms and relationship mechanisms) (Zhang et al, 2012;Liu & Chen, 2015) on inter-organizational knowledge trading and enterprise performance (cooperative performance, innovation performance, etc.). However, in view of the members needing to connect with external suppliers, manufacturers, distributors, retailers and other external social networks in inter-organizational knowledge trading and cooperative innovation, according to the theory of social capital, external social capital of members in supply chain will inevitably affect the organizational context of operation (Hung et al, 2014), and therefore will affect the inter-organizational knowledge trading and cooperative innovation performance in supply chain.…”
